Download or read book Inventory Control of Large Scale Multi Item System with Minimum Order Quantity Constraint and Non Stationary Demand written by Gaetan Deletoille and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We consider a large scale multi-item periodic-review stochastic inventory system with Minimum Order Quantity (MOQ) requirements on the total order size of all items. The item demands are stochastic and non-stationary. The retailer must decide at each time period whether and how many of each item to order from the supplier. The goal is to maximize the reward generated by satisfying the end customers demands while minimizing the costs of holding unsold inventory. We introduce a parameterized heuristic, the w-policy, that relies on our detailed analysis of the problem.We demonstrate the scalability of this heuristic up to ten thousand items, which is unmatched in the literature on the non-stationary demand version of the MOQ problem. The results of our numerical study on large scale real world data sets exhibit the efficiency of the w-policy in these challenging settings. Moreover, our numerical study shows that the w-policy performs at least as well as the state-of-the-art method (S,T) on the simplified problem when the demand is considered stationary, while being more robust in a real supply chain environment.Our results therefore indicate that the w-policy is more robust, has a larger scope of applicability, and is significantly more scalable than state of the art methods for multi-item stochastic inventory control with MOQ requirements.
Download or read book Optimization and Inventory Management written by Nita H. Shah and published by Springer Nature. This book was released on 2019-08-31 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses inventory models for determining optimal ordering policies using various optimization techniques, genetic algorithms, and data mining concepts. It also provides sensitivity analyses for the models’ robustness. It presents a collection of mathematical models that deal with real industry scenarios. All mathematical model solutions are provided with the help of various optimization techniques to determine optimal ordering policy. The book offers a range of perspectives on the implementation of optimization techniques, inflation, trade credit financing, fuzzy systems, human error, learning in production, inspection, green supply chains, closed supply chains, reworks, game theory approaches, genetic algorithms, and data mining, as well as research on big data applications for inventory management and control. Starting from deterministic inventory models, the book moves towards advanced inventory models. The content is divided into eight major sections: inventory control and management – inventory models with trade credit financing for imperfect quality items; environmental impact on ordering policies; impact of learning on the supply chain models; EOQ models considering warehousing; optimal ordering policies with data mining and PSO techniques; supply chain models in fuzzy environments; optimal production models for multi-items and multi-retailers; and a marketing model to understand buying behaviour. Given its scope, the book offers a valuable resource for practitioners, instructors, students and researchers alike. It also offers essential insights to help retailers/managers improve business functions and make more accurate and realistic decisions.

Download or read book Models for Multi Item Inventory Systems with Constraints written by William Edward Daeschner (Jr) and published by . This book was released on 1975 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Constrained multi-item inventory systems with stochastic demands are addressed. The concept of Bad Buys is introduced and their temporal development is studied through a model which links the financial and line-item inventory control subsystems. The interaction of budget constraints and control policies having stochastic resource requirement are examined using a queueing model. Some line-item control systems in current use are shown to be incompatible with budget constrained financial control mechanisms. A model and solution procedure are furnished to guide the line-item inventory control subsystem in exercising adaptive control of a multi-item inventory with stochastic demands and fixed resources provided in successive fiscal periods. An interactive FORTRAN computer program is furnished which exploits the Generalized Lagrange Multiplier procedure in obtaining optimal or near-optimal integer solutions to a class of non-linear integer programming problems.

Download or read book Inventory Control written by Sven Axsäter and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modem information technology has created new possibilities for more sophisticated and efficient control of supply chains. Most organizations can reduce their material flow costs substantially. Inventory control techniques are very important components in this development process. A thorough understanding of relevant inventory models is a prerequisite for successful implementation. I hope that this book will be a useful tool in acquiring such an understanding. Nearly ten years ago I wrote a Swedish book on inventory control. This previous book has been used in courses in production and inventory control at several Swed ish engineering schools and has also been appreciated by many practitioners in the field. Positive reactions from many readers have occasionally made me contemplate writing a new book in English on the same subject. Encouraging support of this idea from the Kluwer Editors Fred Hillier and Gary Folven finally convinced me to go ahead with the project. The result is this new book, which in many ways differs from its Swedish prede cessor. Some differences are due to recent developments in inventory control. Fur thermore, this new book is in a sense more theoretical. In particular, it is to a larger extent focused on creating a good basic understanding of different possible ap proaches when analyzing inventory models.

Available in PDF, EPUB and Kindle. Book excerpt: The paper is concerned with a multi-product dynamic nonstationary inventory problem in which the system is reviewed at the beginning of each of a sequence of periods of equal length. The model has the following features. There is a general demand process with no stationarity or independence assumptions, partial or complete backlogging of unfilled demand, a fixed nonnegative delivery lag (which may be positive only under complete backlogging), a nonstationary linear ordering cost, a nonstationary holding and shortage cost function, discounting of future costs, and nonstationary restrictions like budget and storage limitations. The objective is to choose an ordering policy that minimizes the expected discounted costs over an infinite time horizon. Conditions are given that ensure that the base stock ordering policy is optimal and that the base stock levels in each period are easy to calculate. (Author).

Download or read book Multi Echelon Inventory Management for a Non Stationary Capacitated Distribution Network written by Alvaro Maggiar and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present an inventory management solution for a non-stationary capacitated multi-echelon distribution network involving thousands of products. Assuming backlogged sales, we revisit and leverage the seminal multi-echelon inventory management results in the literature to establish the structural properties of the problem, and derive an efficient and practical solution method. In particular, we describe how the additive separability nature of the objective function can be used in a dynamic programming framework to circumvent the usual curse of dimensionality inherent to high-dimensional inventory management problems. We incorporate features such as asynchronous replenishment intervals at the different echelons, accounting of perishability, capacity constraints (both volume and flow), stochastic lead times, reverse logistics, supply risk and risk-pooling. Illustrative examples demonstrate some of these features.A version of this model was tested at a large grocery retailer in a two-layer network, resulting in a statistically significant increase of availability, sold units, and revenue, while lowering inventory volume at the hub.
